ABSTRACT:
Method and device for stapling stacks of sheets situated in bins placed one above another in parallel with a stapler movable along the bins, the stapler being rotatable about an axis of rotation so as to move the stapler at each bin from an inoperative position, in which the stapler is turned away from the bins, to an operative position, in which the stapling elements of the stapler surround an edge portion of the stack of sheets to be stapled, the stapler having a pressure surface which, during this rotatory movement, pushes to one side of an adjacent bin a stack of sheets already stapled and positioned in the adjacent bin.
